CONDENSER-HEAD FOR EXHAUST-@IFES OF STEAM-ENGINES..

SPECIFICATION forming part of Letters Patent No. 298,698, dated May 13, 1884.

Application filed September 10, 1883. (No model.)

To all whom, t may concern.-

Beit known that I, Wrnnnnn C. LYMAN, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Condenser-Heads for Exhaust-Pi pes of Steam-Engines; and I do hereby declare that the following is a full, clear, and eXact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

lThe object of my invention is to provide a condensinghead for the exhaust-steam pipe of noncondensing steam-engines which will so condense the steam that the moisture in the steam that issues from the same will hardly be perceptible. This I accomplish by the use of the exhaust-head patented to me July 4, 1876, No. 179,581, and the addition thereto of certain auxiliary and sub defiectors arranged in such a manner as to present the utmost possible condensing-surface consistent with safety, by providing said auxiliary deflectors with upturned edges to collect and hold the liquids of condensation, which aids in the process of condensation of the steam, and by flaring outward the edges of the sub-deflectors.

In the drawings, Figure 1 is a vertical section of my exhaust-head. Fig. 2 is a side elevation of the lower deiiector, and Fig. 3 is a perspective view of the same. Fig. et is a detail view.

In the drawings, A represents the top end of a vertical exhaust-pipeleading from a noncondensing steam-engine.

`B is an nverted-cone-shaped shell secured to said exhaust-pipe a suitable distance below the mouth of the same.

C is the head closing the top ofthe inverted shell B, which dips in toward the center, where it is provided with an opening, c, about the same diameter as the exhaust-pipe A.

Depending into the exhaust-head from and encircling the edgesv of the opening c is an escape-pipe, D.

D and E are the upper and lower delectors, the former, D', of which surrounds and depends from the escape D, and the latter, E, of which is inverted, and is suspended a little below the upper deflector by means of the straps a a from the inner contiguous surface of the shell B or said upper deiiector, in the manner shown. rllhe relative positions of the upper and lower deiiectors are such that there is a suitable space left between their contiguous rims or edges, through which the steam escapes on its way to the escape-pipe D.

In the bottom of the lower delector is an opening, c, by means of which the products of condensation are drained from the chamber formed by said upper and lower deflectors into the conduits d d, which, being placed diametrically over and above the mouth of the exhaustpipe A, carry the condensed steam beyond the circumference of the current of steam issuing therefrom to the incline b, made just above where the shell B is connected tol the pipe A, which receive and convey the products of condensation to the drip-pipe F, by which it is carried off. These conduits d d forni a water-shed for the liquids they receive, and are therefore connected. They are soldered or riveted to the sides of the lower de- Hector, as shown in Figs. 2 and. 3. In the original head the upper edges of the side walls of the conduits are flanged or curved outward, and the outer edges of the upper and lower deiiectors are curved, respectively, upward and downward, to assist the process of condensation.

In describing my improved head I have thus far confined myself to the aforesaid patented head. In this original head the current of steam as it issues from the exhaust-pipe is deiiected outward toward the sides of the shell by the lower deflector, thence it is driven either by its own force or that of the following pulsation of steam to the chamber above and around the upper deflector, from which it escapes into the chamber between the two deflectors, and then out of the escape-pipe.

My improvements consist, principally, in the additional means for increasing the condensingsurface, which are placed directly in the path of the escaping current without creating back-pressure, and yet keep the steam within the head as long as possible, in order to deprive it of as much moisture as possible.

As hereinbefore stated, in the original head the top edges of the side walls of the conduits (l were flanged outward. In my improved head I prefer to roof over the conduits and extend the side edges of the roof of the same beyond the sides of the conduits, curving the same upward slightly, so that the products of condensation deposited thereon may drain down the incline of the same into the conduits near their mouths.

On the same horizontal plane with the point where the roofs of the conduits d are connected to the lower delector is a downwardly and outwardly projecting flange constituting a continuation of that part of the roof of the conduit d which extends beyond the side wall of the same. This flange describes a segment around the lower deflector from one conduit to the other, and the whole forms a sub-deflector, E. The lower edge of the flange of this sub-deflector is slightly curved outward, so as to aid the globules of water formed or deposited thereon, and prevented, to a very large extent, from dropping off the sameby the continuous upward current of steam, to seek the roofs of the conduits, where, without obstruction, they can drain off. If desired, I do not consider it beyond the scope of my invention to add one o r more sub-deflectors which shall encircle said lower deflector between the sub-deilector E and the upper curved edges of the said lower deflect- 0r E.

,Projecting inward and downward from the shell B, a little above the horizontal plane of lthe said sub-defiector E', is the auxiliary deflector G, having its outer edges curved upward, so asto hold the products of condensation. This auxiliary deflector serves to anticipate the outskirts of the upward current of steam issuing from the exhaust-pipe, and that which has been deflected downward and outward by deflector E and its sub-deflector. The water held by the upturned edges of this deflector G aids the process of condensation by collecting the moisture coming in contact with it. There may also be one or more of these auxiliary defiectors G; but in this event it is deemed best they should correspond in numbers and position to the additional subdeflectors E. Y

Projecting inward and slightly downward from that part of the shell B which borders the chamber above and around the upper deflector, D, is an auxiliary deflector, H, having its edges upturned to collect and hold the condensed steam for the same purpose as those of the auxiliary deflector G. This auxiliary deflector serves to break the regularity and symmetry of an inward evolute the current of l steam would otherwise make, and furnishes curved portion of the edges of the upper defiector, D', is a sub-deflector, g, the lower edges of which are slightly liared outward. This deflector narrows the opening between the contiguous edges of the upper and lower deliectors, and is so arranged that the current of steam may be guided down into the lower deflector, to carry the remaining moisture and globules of condensed steam formed on the iiared lower edge of the sub-defiector'g through the opening e of the dcflector E into the conduits d, by which they are carried off.

Special attention is directed to the curvature or flaring outward of the sub-deiiector g' and flange ofthe sub-deflector E', which materially improves the function which they are designed to perform, as by references to the foregoing description will be evident.

I'ha'ye mentioned the fact that a hand-hole, B', is made in the shell B. As it is evident that the purpose designed for it is to cleanse the interior of the head, I do not deem it a departure from my invention if two hand-holes instead of one is used-viz., one in the side shell, and another in the head C of the exhaust-head. Moreover, I do not wish to be confined to the exact construction of the head shown, as it is obvious that it can be made to suit the position;

I do not wish to be understood as herein confining myself to the use of deectors D and E having curved outer riins or edges, for my improvements can operate, so far as they individually are concerned, just as well with defiectors not having curved outer rims or edges as with deectors having them. Moreover, it is not absolutely necessary that the auxiliary deflectors G and H should have upwardlycurved rims or edges, for, although such construction is preferred, said deilectors are operative without such conformation.

What I claim as new, and desire to secure by Letters Patent, is-

l. The combination of the deflector E, subdeflector E', and the shell B, substantially as set forth.

2. In an exhaust-head, the combination of the shell B, deflector having outwardly-flared edges E, vsub-deiiectorE, and auxiliary deflector G.

3. In an exhaust-head, the combination of the shell B, and deectors D and E with the auxiliary deflector G, as set forth.

4. The combination of the shell B and the upper deector provided with the sub-deector IOO IIO

g, the lower edges of which are slightly flared.

the shell B, theupper dedeetor, the lower deiector, and the auxiliary deiieotor H, substantially as specified.

In testimony that I claim the foregoing as my own I hereunto affix my signature in pres- 15 ence of vtwo witnesses.
